Often electronic equipment is damaged due to a sudden power outage. This often happens due to uncertain natural conditions, forcing PLN to carry out maintenance on its electricity distribution equipment. In addition, many electrical equipment can be damaged by sudden power outages. To be able to overcome this, people usually use generator to overcome supply failures manually. Based on this background, the author created an Automatic Transfer Switch (ATS) – Automatic Main Faillure (AMF) based on the STM32F103C8T6 microcontroller which is applied to generators when there is a power outage. The ATS – AMF device is made using Relays, PZEM004T Voltage Sensors, magnetic contactors, Miniature Circuit Breakers, stepdown circuits, LCD TFT and STM32F103C8T6 as control systems. This system uses the Fault Tolerance method so that the system can continue to run even if there is damage to the main battery by adding a backup battery as a backup. The results of this study, the Automatic Transfer Switch (ATS) circuit found that the average time needed for the generator to start is 2.5 seconds and the time needed for the generator to produce a stable voltage is 5.7 seconds, thus this time is used as the author's reference in determining the right time to switch the load on the microcontroller so that the load is not damaged due to unstable generator voltage. Whereas in the Automatic Main Failure (AMF) it was found that the Stepdown circuit used to detect whether or not PLN electricity was very responsive because the stepdown circuit was installed in parallel at the PLN source and can be proven by the results in the Arduino application.

The rapid development of technology has created various conveniences in all aspects of human life. One of the fields of technology that is rapidly developing is the world of electronics, which demands digitization to facilitate human activities. For example in the field of trade, humans want a process that is practical and easy. Weight measurement is one of the problems that hinders the trading process, because it is still done manually and is less efficient. The purpose of making a design of automatic digital scales based on fruit images using the yolo method (you only look once) is to determine the type and weight of fruit using a Load Cell sensor simultaneously and accurately. The working principle of this tool is the first, the detection of fruit types is processed by a USB Webcam by taking video from the Webcam and then processing it using the Yolo method to identify the type of fruit. The second stage is input from the Load Cell sensor sending object data read to the Raspberry Pi as the main controller. to determine the weight of the fruit, then the last stage is displayed on the LCD and the results can be printed out as proof of purchase receipt. From the LCD directly displays output in the form of price, weight and type of object being weighed. The Yolo method can detect objects and colors and has high detection speed and accuracy.

Citra satelit yang ideal adalah citra satelit yang mempunyai tingkat tutupan awan (awan tebal maupun haze) yang sangat rendah atau bahkan bebas awan sama sekali, yang disertai dengan tingkat sudut perekaman dari citra satelit tersebut yang juga rendah. Dengan tingkat tutupan awan yang rendah atau tidak ada awan sama sekali, kita dapat melihat keseluruhan obyek-obyek yang terdapat pada citra satelit sehingga kita mendapatkan informasi seutuhnya yang kita inginkan dari data citra satelit tersebut. Tingkat tutupan awan yang terlalu besar menjadi penghambat pada saat menganalisa citra satelit Aqua MODIS sehingga sebagian besar obyek-obyek tidak dapat diidentifikasi. Untuk mengurangi dampak merugikan tersebut, dapat dilakukan proses cloud remove pada data citra satelit Aqua MODIS. Sehingga citra satelit bebas awan dapat dimanfaatkan untuk analisa kandungan klorofil-a fitoplankton di perairan Madura. Pada penelitian ini cloud removal berbasis kloning informasi digunakan untuk menghilangkan bagian dari citra satelit yang terkontaminasi oleh awan. Metode ini membuang bagian dari citra satelit yang terkontaminasi oleh awan. Selanjutnya bagian informasi yang hilang ditutup kembali dengan melakukan klon informasi dari citra satelit lainnya yang bebas awan dengan asumsi bagian citra yang dihilangkan koordinat lokasi dan tutupan lahannya tidak berubah.Tahap deteksi awan dengan thresholding dilakukan untuk memastikan letak lokasi / region yang terkontaminasi awan dan merekonstruksi kembali data yang hilang setelah proses cloud removing. Citra satelit Aqua MODIS yang diujicobakan berhasil mengurangi region yang tertutup oleh awan
